Common Causes and Risk Factors
Direct skin-to-skin contact during an active outbreak
Oral sex or unprotected intercourse with an infected partner
Exposure to a partner's active sores
Weakened immune system (stress, illness)
Pregnancy and risk of neonatal exposure to HSV
Signs and Symptoms
Tingling, itching, or burning sensation before blisters appear
Clusters of red, fluid-filled blisters on the mouth or genitals
Painful sores that crust over and heal in 2-3 weeks
Urethral pain, discharge, or fever in males (HSV-2)
Some people have mild or no symptoms but can still spread the virus
How Dr. Nghia Nguyen Diagnoses This Condition?
Dr. Nguyen uses a step-by-step approach:
Medical History and Physical Exam
He reviews your symptom history, outbreak frequency, sexual practices, and other risk factors. A focused exam inspects any active sores or prodromal signs (tingling, burning).
Lesion Swab and Viral Testing
When sores are present, Dr. Nguyen collects a swab for PCR or viral culture—this provides rapid, type-specific confirmation (HSV-1 vs. HSV-2).
Blood Tests for Antibodies
Serologic testing checks for HSV-1 and HSV-2 antibodies to detect past or asymptomatic infections and guide long-term management.
Additional Evaluation (if indicated)
In complex or recurrent cases, he may order HIV screening or partner testing, and assess immune status to tailor suppressive therapy.

Frequently Asked Questions
What is the difference between HSV-1 and HSV-2?
HSV-1 usually causes oral cold sores, while HSV-2 typically leads to genital outbreaks. Both types can infect either area through direct contact.
Can men have HSV-2 without visible sores?
Yes. Many men experience mild or no symptoms yet still carry and can transmit the virus. Blood tests or swabs confirm the diagnosis.
How do I recognize early-stage HSV in babies?
Watch for fever, irritability, poor feeding, or clustered skin blisters. If you suspect HSV in a newborn, seek immediate medical evaluation.
Is there a cure for herpes simplex virus?
Currently, there's no cure. Antiviral medications like acyclovir or valacyclovir control outbreaks, reduce severity, and lower transmission risk.
Can I transmit HSV when I have no symptoms?
Yes. Asymptomatic viral shedding can occur between outbreaks. Daily suppressive therapy reduces—but does not eliminate—the risk of transmission.
How long does an HSV outbreak last?
First outbreaks often last 2-3 weeks. Recurrent episodes are usually shorter—about 3-7 days with antiviral treatment.
